The Djed Pillar is an Egyptian object that symbolizes the triumph of justice. Resembling a ridged upright pillar, it is believed to represent the spine of the dead king Asar Osiris.
The first day of Shemu on the Egyptian calendar marked the Festival of the Raising the Djed Pillar. The festival celebrated the ascension of Asar to the throne of the Tuat (underworld), following the rightful return of the throne of Egypt to his son Heru (Horus)-- after a long ordeal involving Asar's brother, Suti (Set). The struggle between Heru and Suti would be reenacted as part of the festivities.
